7 the other hand, a liquid crystal display device 4 is disposed inside the lid case 2 as described above. A
protective glass panel 5, 51 is provided facing opposite surfaces of the display device 4. Thus, the inner protective glass panel 5 forms the inner display surface 21, and the rear protective glass panel 51 forms the outer display surface 22. Disposed on the interior of the lid case 2 are a liquid crystal display driver 8, speaker 24, and folding detection switch 7.
The liquid crystal display device 4 has the same construction as in the prior art. With reference to FIG.
3, the device 4 comprises a liquid crystal material 41, X
electrodes 42 and Y electrodes arranged with a predetermined pitch respectively on opposite sides of the liquid crystal material 41, and two polarizers 46, 47 disposed respectively on the outer sides of the electrode arrangements, with a glass plate 44 or 45 interposed between each polarizes and the corresponding electrode arrangement.

protective glass panel 5, 51 is provided facing opposite surfaces of the display device 4. Thus, the inner protective glass panel 5 forms the inner display surface 21, and the rear protective glass panel 51 forms the outer display surface 22. Disposed on the interior of the lid case 2 are a liquid crystal display driver 8, speaker 24, and folding detection switch 7.
The liquid crystal display device 4 has the same construction as in the prior art. With reference to FIG.
3, the device 4 comprises a liquid crystal material 41, X
electrodes 42 and Y electrodes arranged with a predetermined pitch respectively on opposite sides of the liquid crystal material 41, and two polarizers 46, 47 disposed respectively on the outer sides of the electrode arrangements, with a glass plate 44 or 45 interposed between each polarizes and the corresponding electrode arrangement. The two polariziers 46, 47 are used in combination with their polarization directions positioned orthogonally to each other, and the molecules of the liquid crystal material 41 are twisted through 90 degrees
8 as positioned between the two polarizers 46, 47. With no voltage impressed across the X electrode 42 and the Y
electrode 43, light is propagated as twisted through 90 degrees along the twist of the liquid crystal molecules and therefore passes through the polarizers 46, 47.
However, voltage applied eliminates the twist of the liquid crystal molecules, with the result that light fails to pass through the polarizers 46, 47. Utilizing these phenomena, the device 4 displays images on the display screen provided by the liquid crystal material 41.
With the liquid crystal display device 4, therefore, the image display screen provided by the liquid crystal material 41 is transparent, and the images displayed on the screen can be observed from both the front side and rear side thereof.
Further with the display device 4, the intersection of a pair of X electrode 42 and Y electrode 43 serves as one pixel, and one character can be formed by a plurality of pixels as seen in FIG. 4(a). For example, in the case where the character "a" is to be displayed on the screen which is to be observed from the front side thereof, a usual display pattern is produced as shown in FIG. 4(a).
electrode 43, light is propagated as twisted through 90 degrees along the twist of the liquid crystal molecules and therefore passes through the polarizers 46, 47.
However, voltage applied eliminates the twist of the liquid crystal molecules, with the result that light fails to pass through the polarizers 46, 47. Utilizing these phenomena, the device 4 displays images on the display screen provided by the liquid crystal material 41.
With the liquid crystal display device 4, therefore, the image display screen provided by the liquid crystal material 41 is transparent, and the images displayed on the screen can be observed from both the front side and rear side thereof.
Further with the display device 4, the intersection of a pair of X electrode 42 and Y electrode 43 serves as one pixel, and one character can be formed by a plurality of pixels as seen in FIG. 4(a). For example, in the case where the character "a" is to be displayed on the screen which is to be observed from the front side thereof, a usual display pattern is produced as shown in FIG. 4(a).
9 On the other hand, when the display device 4 is reversed by turning upside down to observe the device 4 from the rear side thereof, as shown in FIG. 4(b), the display pattern is reversed in symmetric relationship about a horizontal line, whereby the character "a" can be observed normally even when the device 4 is reversed by turning upside down.
With the foldable portable telephone of the invention, when the user observes the image on the inner display surface 21 with the lid case 2 open, as seen in FIG. 1(a), the usual display pattern is produced as in the prior art. With reference to FIG. 1(b), when the user observes the image on the outer display surface 22 with the lid case 2 closed, the display pattern as reversed is produced on the liquid crystal display device as described above. This enables the user to observe the image in normal position regardless of the state of the lid case.
FIG. 5 shows the operation to be performed when a call is received by the foldable portable telephone.
When the call is received in step Sl, step S2 prepares a usual display pattern representing information which l indicates the telephone number of the caller and the reception of the call, and thereafter the folding detection switch is checked whether it is on or off in step S3. If the lid case is opened, the folding detection switch is found off followed by step S7 transmitting the data constituting the display pattern to the display driver. As a result, the image is presented on the display device to enable the user to observe the image through the inner display surface 21 in step S8.
On the other hand, when the lid case is closed in step S3, the folding detection switch is found on, and then step S4 follows to have the display pattern reversed.
Step SS follows to transmit the data constituting the reversed display pattern to the liquid crystal display driver. Consequently, in step S6 the image is displayed on the display device, and the image can be observed normally through the outer display surface 22.
Further, in the case where a call is received with the lid case closed and then the lid case is open, step S6 follows step S7 and the display pattern returns to the normal pattern to be presented on the liquid crystal display in step S8.
FIG. 6 (a)(b) show an example of the display patterns produced on the display device 4 with the lid case 2 open and an example of the display patterns on the display device 4 with the lid case 2 closed, and each of which is observed through the front surface of the display device 4. As shown in FIG. 6(b), whereas the display pattern is reversed with the lid case 2 closed, the pattern can be observed normally through the outer display surface 22.
Upon receiving a call, the foldable portable telephone of the invention enables the user to view the telephone number of the caller, etc. without opening the lid case as described above, and is therefore convenient.
Further the invention wherein the single liquid crystal display device 4 is used to provide the inner display surface 21 and the outer display surface 22 results in a lower cost and a smaller space than the use of two liquid crystal display devices for providing an inner display screen and an outer display screen.
The telephone of the present invention is not limited to the foregoing embodiment in construction but can be modified variously by one skilled in the art without departing from the spirit of the invention. The control circuit board 6 or liquid crystal display driver 8 is operated for producing a reversed image display pattern for presentation on the openable lid case.
Whereas the image display pattern of the display device is reversed with the lid case closed according to the procedure of FIG. 5 (step S4), it is alternatively possible to produce an image display pattern which is observed normally through the outer display surface 22 in the display device with the lid case 2 closed and to reverse the display pattern by opening the lid case 2.
With the construction shown in FIGS. 1(a), 1(b) and 2, the display device 4 is turned upside down and reversed by opening the lid case 2 so that the image display pattern is reversed in symmetric relationship about a horizontal line, whereas if the display device is adapted to be turned laterally and reversed by opening the lid case, the image display pattern may be reversed in symmetric relationship about a vertical line.
With the foldable portable telephone of the invention, when the user observes the image on the inner display surface 21 with the lid case 2 open, as seen in FIG. 1(a), the usual display pattern is produced as in the prior art. With reference to FIG. 1(b), when the user observes the image on the outer display surface 22 with the lid case 2 closed, the display pattern as reversed is produced on the liquid crystal display device as described above. This enables the user to observe the image in normal position regardless of the state of the lid case.
FIG. 5 shows the operation to be performed when a call is received by the foldable portable telephone.
When the call is received in step Sl, step S2 prepares a usual display pattern representing information which l indicates the telephone number of the caller and the reception of the call, and thereafter the folding detection switch is checked whether it is on or off in step S3. If the lid case is opened, the folding detection switch is found off followed by step S7 transmitting the data constituting the display pattern to the display driver. As a result, the image is presented on the display device to enable the user to observe the image through the inner display surface 21 in step S8.
On the other hand, when the lid case is closed in step S3, the folding detection switch is found on, and then step S4 follows to have the display pattern reversed.
Step SS follows to transmit the data constituting the reversed display pattern to the liquid crystal display driver. Consequently, in step S6 the image is displayed on the display device, and the image can be observed normally through the outer display surface 22.
Further, in the case where a call is received with the lid case closed and then the lid case is open, step S6 follows step S7 and the display pattern returns to the normal pattern to be presented on the liquid crystal display in step S8.
FIG. 6 (a)(b) show an example of the display patterns produced on the display device 4 with the lid case 2 open and an example of the display patterns on the display device 4 with the lid case 2 closed, and each of which is observed through the front surface of the display device 4. As shown in FIG. 6(b), whereas the display pattern is reversed with the lid case 2 closed, the pattern can be observed normally through the outer display surface 22.
Upon receiving a call, the foldable portable telephone of the invention enables the user to view the telephone number of the caller, etc. without opening the lid case as described above, and is therefore convenient.
Further the invention wherein the single liquid crystal display device 4 is used to provide the inner display surface 21 and the outer display surface 22 results in a lower cost and a smaller space than the use of two liquid crystal display devices for providing an inner display screen and an outer display screen.
The telephone of the present invention is not limited to the foregoing embodiment in construction but can be modified variously by one skilled in the art without departing from the spirit of the invention. The control circuit board 6 or liquid crystal display driver 8 is operated for producing a reversed image display pattern for presentation on the openable lid case.
Whereas the image display pattern of the display device is reversed with the lid case closed according to the procedure of FIG. 5 (step S4), it is alternatively possible to produce an image display pattern which is observed normally through the outer display surface 22 in the display device with the lid case 2 closed and to reverse the display pattern by opening the lid case 2.
With the construction shown in FIGS. 1(a), 1(b) and 2, the display device 4 is turned upside down and reversed by opening the lid case 2 so that the image display pattern is reversed in symmetric relationship about a horizontal line, whereas if the display device is adapted to be turned laterally and reversed by opening the lid case, the image display pattern may be reversed in symmetric relationship about a vertical line.
